OPTICAL-TO-ELECTRIC TRANSDUCER Russian patent published in 1994 - IPC

Abstract RU 2009449 C1

FIELD: measuring devices. SUBSTANCE: when linearly increasing voltage supplies electrostatic plates, electronic beam sweeps over surface of shutter diaphragm and image is framed sequentially by sequential separation of beam into pictures. Beam movement over screen results in defocusing of image. This is prevented by supplying compensated plates with linearly increased voltage having opposite polarity. Absolute compensation of beam movement over screen is achieved by adjusting of position of device insertion which is adjusted by rotation of screw. EFFECT: decreased device transit-time effects during generation of sequence of pictures. 1 dwg
